What is the Serverless architecture?

Do you know what a serverless architecture consists of? A bit of history: more than 50 years ago, ARPANET emerged, a system through which different organizations (mainly military ones) could connect their computers through a network.

Over the years, this technology evolved into today's Internet and businesses began to use it. The problem is, to get their information online, they needed space, expensive equipment, a good cooling system, software, and other resources.

The road was long, and that is why it was necessary to develop the serverless model. Under this technology, other companies take care of the provisioning to facilitate access to the cloud to a greater number of people.

In this way, even though they now exist different solutions that organizations can accessThanks to serverless technology, you do not need anything more than to install the code of an application, thus delegating the management of infrastructure and equipment.

But what is meant by Serverless architecture?

The size of the global market for serverless architecture was valued at $ 3,105.64 million in 2017 and it is expected to reach 21,988.07 million in 2025, but what makes it so important?

To understand it better, you must start with the serverless concepts, that is, aspects such as the terminology and technical bases of this model.

First, the serverless architecture doesn't kill servers, it just takes computing resources into the background because you no longer have to take care of them.

Everything is left to the cloud service provider, and you only pay for what you consume. In this way, you can focus on the continuous improvement of your products / services.

exist different uses you can give to serverless computing, but some examples are those of Coca-Cola, The Seattle Times or Benchling, companies that use the serverless architecture to execute functions.


  • The Coca-Cola Company used it to deploy a low latency web application in 100 days.
  • The Seattle Times uses it to resize images according to the type of device.
  • Benchling, for his part, uses it to modify parts of a genome in a fairly precise way.

You already know some of the serverless concepts and have an idea of what it is for, but who offers these technologies? Today's most popular providers for cloud computing are Amazon and Microsoft. The first developed Amazon Web Services (AWS) and the second, Microsoft Azure.

In both companies they offer you the Serverless architecture, on the one hand, you find it as AWS Lambda; and at Microsoft, like Azure Functions. Although they pursue the same objective, they have their own peculiarities.

What is Microsoft Azure Functions for?

Simply put, Azure Functions is Microsoft's serverless technology. It works by loading code that then responds to certain events.

Many times AWS and Azure are used together to take advantage of the functionalities of both platforms and diversify risk.

However, Azure Functions takes a different approach than Lambda in terms of hosting plans, configurability, and customization, with Azure being a bit more customizable.

On the other hand, the solutions for each platform are different. To work with artificial intelligence, you have SageMaker on AWS and the Machine Learning module on Azure.

Which one is best for you will depend on what you need, so it is important that you understand what Microsoft Azure Functions is for and this is something that a professional consultancy can clarify for you.

In Codster you will find cloud computing experts willing to solve your doubts and guide you in the implementation of the serverless technology that your business needs.
